Common procedures done on sheep and goats 🐐

Caseous lymphadenitis will often affect goats (internal/external?) l.n.s and will affect sheep's (internal/external?)

goats-external sheep-internal-so sheep will be ADR and wasting away

Respiration ·Detected by watching _______________ ·Normal range = ______________ When?

movement of flank 15 - 20 /minute Early in the morning !

-_____________ injections are given behind the elbow joint and in front of the shoulders -Pull out the skin, forming a tent -Insert needle just through the skin and administer drug

subcutaneous

Does vaccinated for ______________ 2 to 4 weeks before kidding

tetanus

Give ____________ at the time of banding if the does are not vaccinated, and a _____________ a week later.

tetanus antitoxin toxoid

True or False? Spending a few minutes every day learning the normal behavior and attitude of your goats or sheep is very important.

true The person that feeds them and watching them is critical. If they don't come up to you, you have a problem. They have very subtle changes to indicate they're sick. Once they start showing clinical signs, it's bad. They're not taken to the vet unless they're dieing. A downer sheep/goat is a dead sheep/goat. The person feeding them noticing them not coming up to them or to eat will first notice they're injured or sick.

Identification

- ear tagging (RFID tags-permanent) - Tattooing - Ear notching

Disbudding Dairy Kids

-10-14 days -Make sure the mother was vaccinated for tetanus during the last 3-4 weeks so she can pass the ABs onto the kid so they don't get tetanus from dehorning -Vaccinated for tetanus-doe (2-4 weeks prior to kidding) -Sedation?

Disbudding older kids: Anesthesia

-Can use nerve blocks-2 nerves supply each horn -Gas anesthesia through a mask-not during actual procedure of using disbudding iron, as a flash fire could result -Xylazine/ketamine -In great Britain it is required by law for heavy sedation or general anesthesia

Disbudding Equipment

-Disbudding iron -Scissors or clippers -Antiseptic -Fly repellant -Restraint technique-hold between legs or use a disbudding box

Docking using a scalpel blade, knife or emasculator

-Find junction of caudal fold at the underside of the tail -Pull skin towards obdy so it remains to cover dock -Cut between vertebra -Make a clean cut-will heal faster -Apply 7% iodine solution

Dehorning Kids>4 weeks of age

-Kids>4 weeks of age disbudding is not very successful (remember the frontal sinus comes up into the horn in the goat) -Deep sedation -Pain medication -Sutures are necessary to close the sinus

Docking Post-Procedure

-Place lambs in pens with clean bedding -Tetanus injection can be given -Heat lamps should be used in cold weather -Don't overcrowd lambs as can contribute to disease outbreak

Why disbud?

-Prevent injury from herd mates fighting -Prevent owner/handler injury -For show purposes, dairy goats to be registered must be dehorned -Prevent destruction of fences, facilities etc. -Less chance the goat will get caught or hung in a fence -Prevent odor to the milk (bc also trying to burn off the scent glands)

How to use the disbudding iron

-Put disbudding iron on the horn for 5-10 seconds -Skin separation and there is a copper colored groove all the way around, and the skin separated from the base of the horn. -If bud is only partially destroyed will have a horn "scur" grow

Wattle removal

-Wattles are frequently found hanging from necks of goats -are nonfunctional -can be a source of injury to the animal and possible site of infection -kids may suck on them causing infection as well -Removal --hold the animal --disinfect the area at the thinnest point of the wattle --disinfect blades of surgical scissors --local anesthesia --pull on wattle and snip at the thinnest point --disinfect wound --usually little or no bleeding

Age to perform disbudding

-Within first 2 weeks of life (he likes to sedate a little after 2 weeks) -European breeds 5-7 days of age -For large buck kids 3-5 days of age -Sedation and nerve blocks are done >2 weeks of age -Cornual nerve block -Lidocaine 2%-20 mg/mL -Lidocaine toxicity! (5 mg/kg) -Meloxican-15 mg pill-half a pill

Docking

Why do you do smart drenching. What is smart drenching?

Drenching and dosing ¨Administering liquids ¨Hold head in your arm and open the mouth by grasping the mandible behind the incisors. ¨Insert syringe or drenching gun over the back of the tongue (generally use with anthelmintic) ¨Pour liquid in slowly to allow animal to swallow ¨Smart drenching He suggests non injectable dewormers because of antibiotic resistance. If put in the front they'll spit it out. When babies are born, they're monogastric. They have esophageal groove. In some animals when they get older, that'll still be there. Then if bring to the front, it might go straight to the abomasum and will get metabolized too fast to be affective.

Castration - surgical ¨Young kids - __________weeks old True or False? Usually done with anesthesia. Why? ¡Older kids and adults - ___________+______________ injected into the testicles ¡Wash scrotal area ¡Remove bottom _________ of scrotum with a clean blade ¡Pull down each testicle, one at a time, by separating the cremaster muscle until ______________ breaks. ¡Remove the testicle.

Banding 10 ► 14 penis < 2 2 - 4 3 - 4 > 4 testicles

Dock when?

Before 2 weeks of age -amputate tail between vertebra at end of caudal folds -if docked too short females could be prone to rectal prolapse in the future from damage to nerves in the perineal area -few blood vessels and nerves in this area

Is a quick easy method of describing how thin or fat goats are, using a numerical score from 1 to 5. A goat may be give a half score, such as 2.5, if it is between BCS 2 and BCS 3. Assigning a BCS cannot be done by looking at the goat, one must feel for muscle and fat cover. An appropriate BCS range for goats is from BCS 2 to BCS 4, as seen on the reverse side. Goats that are too thin (BCS 1) may have nutritional or health problems reducing productivity. Overly fat goats (BCS 5) have reduced fertility, increased birthing problems, and health problems. BCS is commonly assessed in the loin area. Feel the amount of tissue covering the ends of the spinous and transverse processes of the vertebrae. Feel any loin muscles and fat filling the space between the backbone and horizontal bones. In very thin goats the bones can feel "sharp". As the animal gains condition, the thicker tissue covering makes the bone ends feel more rounded and smooth .

Body condition score

Castration - ___________ clamp ¨Does not involve cutting ¨Is bloodless so less chance of infection and fly strike ¨Crushes spermatic cord ¨Restraint animal and manipulate testes down into the scrotum and get cord between fingers ¨Place (answer 1) on the spermatic cord on one side, ¨Don't go down the midline ¨Ensure that the spermatic cord is in jaws and close ¨Hold for 15 - 20 seconds and repeat 1 cm apart ¨Perform on both sides ¨Make sure they are vaccinated for tetanus ¨Evaluate after 1 month to ensure that testicles have atrophied

Burdizzo

Docking using a _______________ -Also used for castration to crush spermatic cord -Place on tail and close handles -Cut off tail inside of clamp -Leave for 5-10 seconds to stop bleeding -Apply 7% iodine solution -Doesn't work on large lambs>4 weeks of age -These clamps may be damaged by use for docking and shouldn't then be used for castration

Burdizzo

-Done to prevent unwanted breeding -Reduce undesirable odors and aggressive behavior in meat goats -Improve meat flavor in goats kept past puberty -Should take place as early as possible -Most castration done at 2-4 weeks of age -Castrating>4 months of age decreases incidence of urinary calculi (like for show animals that are fed a lot of concentrates to get them fat-> not castrating until they get bigger could potentially help prevent urinary calculi)

Castration

-Usually done within a month -give tetanus antitoxin-doe or ewe not vaccinated in the last 2-4 weeks of gestation -Pain meds! -Is bloodless method -Cuts off blood supply, testes and scrotum will slough off in 10-14 days -Need to check animal as infection of scrotum could occur

Castration - Elastrator band

Dehorning box

Dairy goats will be dehorned. Lot of them have scent glands at the base of the horn, and you don't want those sent glands.

Aging of Goats

Dental formula = 0 0 3 3 4 0 3 3 0/4 incisors, 3/3 pre-molars, 3/3 molars. The first number in each formula represents how many sets of teeth are on the upper jaw; the second number indicates how many sets of teeth are on the lower jaw. For example, the 0/4 means that sheep/goats have no upper incisors, but have 4 sets of lower incisors (8 lower incisors in all). Most of the time the dental formula looks like this 2 (0/4 incisors, 3/3 pre-molars, 3/3 molars) = 32. No upper incisors, no canines -look at the gumline, if it's recessing the animal is older (also use common sense and look at the animal)

Examining - no restraint

¨Appetite ¨Feces-supposed to be pelleted. Wet and yellow rear end means you have diarrhea ¨Respiration/cough ¨Grunting-know they are in pain-rolling colicky ¨Grinding their teeth ¨Discharge: nasal, ocular or vaginal-should be clear, not worry. Turn white worry. Allergies/dusty barn-wet area in the medial canthus, pay attention. If one eye, two eyes. ¨Eye sight-running into objects Goats are very picky eaters, and prefer not to eat hay or feed that is 'dirty' or old. Have to change their feed out daily, and also their water. ALSO—feeding them off of the ground helps to minimize the number of parasites they pick up. Pay attention to the one not coming up -Appetite -Feces -Respiration/cough -Grunting -Grinding their teeth -Discharge: nasal, ocular or vaginal -Eye sight -Body Condition -Gait -Lameness -Movement -Swelling -Bloat (will be on the left side, if on both sides GI is possibly involved or enterotoxemia) Picture: Swollen joints, not putting weight on all four->CPE

Not restraint that you can evaluate

¨Body condition ¨Gait-limping? ¨Lameness ¨Movement ¨Swelling ¨Bloat-rumen fills up with gas and extended on left side. Bloated on both sides could have an obstruction. Is it at the top/bottom. Higher rumen, lower something else

Paste Administration

Tubing an animal

¨Hold the head in your arm and open the mouth. ¨Check depth. Place tube outside of the animal from the mouth to inside the rumen, make a mark on the tube, then insert the tube to that mark ¨Place the speculum ¨Insert tube through the speculum in back of the mouth and down the esophagus ¨Administer liquid solution slowly (Precautions) ¡Ensure you enter the esophagus, the tube can either be seen or felt through the throat. Check for smell of rumen fluid. -remember to use the right size tube
